In -20°C or -70°C serum can usually be stored for years, but in some specific cases, this time may be shorter for anti-peptide antibodies. Use the extinction coefficient (ɛ) of rhodamine B (ɛ 555 = 106,000) to determine the concentration of the rhodamine B solution. The concentration of the stock solution measured in the experiments presented here is 4.3 μM. 2. The frequency dependent polarizabilities of closed-shell alkali metal clusters containing up to ten lithium, potassium, and rubidium atoms have been calculated using the linear complex polarization extinction coefficient in photoelectric photometry E. Poretti1, F. Zerbi2 1 Osservatorio Astronomico di 2Dipartiment Brera, Merate,o Italy, Fisica Nucleare e Teorica, Universitd di Pavia, Italy Abstract Observational evidence was found that even in good photometric sites the extinction coefficient can display large variations during a night.

The molar extinction coefficient (ε) for Alexa Fluor 488 is 73,000 cm-1M  22 May 2017 For example, DyLightTM 350 has an extinction coefficient value of 15,000 (dim) As an example, FITC cannot be used with Alexa Fluor® 488. proportional to the product of the extinction coefficient and the quantum yield.

Excitation maximum = 495 nm; emission maximum = 515 nm; extinction coefficient = 73,000 M-1 cm-1; quantum yield = 0.92. Optical Data for TFAX 488, TFP Emission Color

AFDye™ 488 is a bright, highly photostable, green-fluorescent probe optimally excited by the 488 nm laser line. ‡ Extinction coefficient of the reactive dye at emission maximum in cm-1 M-1. § Human vision is insensitive to light beyond ~650 nm; it is not possible to directly view far-red– and near-IR–fluorescent dyes. Datasheet MSDSs. AFDye™ 488 Picolyl Azide is an advanced fluorescent probe that incorporates a copper-chelating motif to raise the effective concentration of Cu (I) at the reaction site to boost the efficiency of the CuAAC reaction, resulting in a faster and more biocompatible CuAAC labeling. Up to 40-fold increase of signal intensity, compared to conventional azides, was reported (see Selected References).

Unless otherwise specified, molar extinction coefficient (ε) values are typically measured in ddH2O or PBS. Need to determine the extinction coefficient of Alexa Fluor® dyes for your experiment? Click the links below to get the data!

Extinction coefficient behaviour with wavelength. The aim of this work is to study the atmospheric extinction coefficients at several wavelengths in different atmospheric conditions (clear and dusty days) over the Canarian observatories. The correlation between the coefficients provides information on the extinction wavelength dependency.

Storing and Handling the Conjugates Store the labeled protein—which will be in PBS, pH 7.2, containing ~2 mM sodium azide—at Alexa Fluor 488 spectrum - Alexa Fluor 488 is a fluo excitation and emission wavelengths using the interactive Spectrum Viewer - A web application for viewing and comparing spectra of various fluorescent compounds. Exportable as image or link. Alexa Fluor 488 is a bright, green fluorescent dye with excitation ideally suited to the 488 nm laser line. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor 488 dye is water soluble and pH-insensitive from pH 4 to pH 10. A large number of rhodamine dyes, including Alexa Fluor 488, Alexa Fluor 532, Alexa Fluor 568, ATTO488, ATTO532, and ATTO565, were found to form stable radical anions upon irradiation in the presence of thiol compounds such as β-mercaptoethylamine (MEA).
